ARRANGEMENT AND METHOD FOR OPERATING AN ARRANGEMENT

摘要

The invention relates to at least one embodiment of a method which is set up to operate an arrangement (1). The arrangement (1) has N radiation-emitting semiconductor chips (2). The semiconductor chips (2) are arranged in an electric series circuit. The arrangement (1) comprises multiple switching elements (3), wherein to each of the semiconductor chips (2) one of the switching elements (3) is connected electrically in parallel. The arrangement (1) includes an activation unit (4) for the mutually independent activation of the switching elements (3). The arrangement (1) comprises a constant current circuit (5) for energizing the series circuit. When switching off, the respective semiconductor chip (2) associated with a switching element (3) is bridged electrically by the switching element (3). A protective module (6) of the arrangement (1) is set up to reduce or to prevent current peaks when one or more of the semiconductor chips (2) is/are switched off.
